PRINTED CIRCUIT BOARD, AND CHIP TYPE SOLID ELECTROLYTIC CAPACITOR MOUNTED ON THE SAME

摘要

PROBLEM TO BE SOLVED: To enable a printed circuit board, which is used in various electronic instruments and mounted with a chip type solid-state electrolytic capacitor, to be reduced more in ESL. SOLUTION: The printed circuit board is mounted with a chip type solid-state electrolytic capacitor of four-terminal structure where anode terminals and cathode terminals are arranged at the two opposed positions intersecting each other. The anode terminals and cathode terminals of the chip type solid-state electrolytic capacitor are configured in such a manner that an anode electrode pattern 2 composed of a pair of the soldered anode electrodes and a cathode electrode pattern 4 composed of a pair of the cathode electrodes are provided and that an inductor 3 is provided so as to electrically connect the anode electrode patterns 2 together, so that aπfilter is formed to reduce the ESL of the printed circuit board remarkably.
